What is the Caterpillar EGR system called?

• A. Clean Gas Induction
• B. Clean Gas Recirculation
• C. Gas Induction Clean
• D. Induction Gas Clean

Answer: (A)

Caterpillar labels its Exhaust Gas Recirculation system as Clean Gas Induction. The idea behind EGR is to send a portion of exhaust back into the intake to dilute the incoming air and lower combustion temperatures, which helps cut NOx emissions. The word “clean” in this name conveys that the recirculated gas is conditioned—cooled and managed—to minimize deposits before it re-enters the engine. In CAT literature you’ll often see the acronym CGI, short for Clean Gas Induction, used to refer to this system. The other phrasings don’t match Caterpillar’s branding and would not be recognized as their term for the EGR setup.
